8.4 Operating modes
The following operating modes are possible:
● Operating without control unit
● Operation via an external control unit
● Operation via RS-485 and Pfeiffer Vacuum display and control unit or PC
Automatic start
After bypassing the contacts at pins 2, 7 and 5 on the “remote” connecting plug or when
using a connecting cable with respective bridges and applying the supply voltage, the vac-
uum pump starts up immediately.
Pfeiffer Vacuum therefore recommends switching on the voltage supply immediately before
operation.
Operate without control unit
► Provide the current supply.
After applying the operating voltage, the vacuum pump carries out a self-test to check the supply volt-
age.
Operate via the external control
► Connect the remote control via the "remote" 15-pin D-Sub socket.
The control is carried out by means of "PLC level".
Operate with peripheral devices or PC
1. When handling the Pfeiffer Vacuum display and control units, observe the respective operating in-
structions:
– Operating instructions at the
.
2. Connect the respective peripheral device to the 15-pin D-Sub socket.
3. Make the desired settings via the RS-485 using the peripheral device.
